Sentence examples for reproduction changes from inspiring English sources

Thus, in female flies actively engaged in reproduction, changes in both intestinal progenitors and their progeny parallel those observed in mammals leading to hyperplasia (Hammond, 1997; Speakman, 2008), increased organ size (Hammond, 1997; Speakman, 2008) and upregulation of lipid gene expression (Athippozhy et al., 2011).

Using AFLP markers, we examined 12 populations of the expansive grass Brachypodium pinnatum differing in habitat age (30 50, ca. 100 and >300 years old) in order to determine whether clonal diversity of populations, genetic variation, and the relative importance of clonal propagation versus sexual reproduction change with grassland age.

The model provides a good qualitative reproduction of changes in gene expression over time.

Due to its complex life cycle and extreme long distance migrations, A. anguilla is an intriguing model in which to investigate reproduction related changes in the brain.
